Here’s a puzzle I’ve thought about a few times recently:
The impact of an activity (I) is due to two factors, X and Y. Those factors combine multiplicatively to produce impact. Examples include:
The funding of an organization and the people working at the org
A manager of a team who acts as a lever on the work of their reports
The EA Forum acts as a lever on top of the efforts of the authors
A product manager joins a team of engineers
Let’s assume in all of these scenarios that you are only one of the players in the situation, and you can only control your own actions.
From a counterfactual analysis, if you can increase your contribution by 10%, then you increase the impact by 10%, end of story.
From a Shapley Value perspective, it’s a bit more complicated, but we can start with a prior that you split your impact evenly with the other players.
Both these perspectives have a lot going for them! The counterfactual analysis has important correspondences to reality. If you do 10% better at your job the world gets 0.1I better. Shapley Values prevent the scenario where the multiplicative impact causes the involved agents to collectively contribute too much.
I'm annoyed at vague "value" questions. If you ask a specific question the puzzle dissolves. What should you do to make the world go better? Maximize world-EV, or equivalently maximize your counterfactual value (not in the maximally-naive way — take into account how "your actions" affect "others' actions"). How should we distribute a fixed amount of credit or a prize between contributors? Something more Shapley-flavored, although this isn't really the question that Shapley answers (and that question is almost never relevant, in my possibly controversial opinion).
Happy to talk about well-specified questions. Annoyed at questions like "should I use counterfactuals here" that don't answer the obvious reply, "use them FOR WHAT?"
I don’t feel 100% bought-in to the Shapley Value approach, and think there’s a value in paying attention to the counterfactuals. My unprincipled compromise approach would be to take some weighted geometric mean and call it a day.
FOR WHAT?
Let’s assume in all of these scenarios that you are only one of the players in the situation, and you can only control your own actions.

I think you're right to be more uncomfortable with the counterfactual analysis in cases where you're aligned with the other players in the game. Cribbing from a comment I've made on this topic before on the forum:
I think that counterfactual analysis is the right approach to take on the first point if/when you have full information about what's going on. But in practice you essentially never have proper information on what everyone else's counterfactuals would look like according to different actions you could take.
If everyone thinks in terms of something like "approximate shares of moral credit", then this can help in coordinating to avoid situations where a lot of people work on a project because it seems worth it on marginal impact, but it would have been better if they'd all done something different. Doing this properly might mean impact markets (where the "market" part works as a mechanism for distributing cognition, so that each market participant is responsible for thinking through their own alternative options, and feeding that information into the system via their willingness to do work for different amounts of pay), but I think that you can get some rough approximation to the benefits of impact markets without actual markets by having people do the things they would have done with markets -- and in this context, that means paying attention to the share of credit different parties would get.
Shapley values are one way to divide up that credit. They have some theoretical appeal, but it's basically as "what would a fair division of credit be, which divides the surplus compared to outside options". And they're extremely complex to calculate so in practice I'd recommend against even trying. Instead just think of it as an approximate bargaining solution between the parties, and use some other approximation to bargaining solutions -- I think Austin's practice of looking to the business world for guidance is a reasonable approach here.

So, as a self-professed mechanism geek, I feel like the Shapley Value stuff should be my cup of tea, but I must confess I've never wrapped my head around it. I've read Nuno's post and played with the calculator, but still have little intuitive sense of how these things work even with toy examples, and definitely no idea on how they can be applied in real-world settings.
I think delineating impact assignment for shared projects is important, though I generally look to the business world for inspiration on the most battle-tested versions of impact assignment (equity, commissions, advertising fees, etc). Startup/tech company equity & compensation, for example, at least provides a clear answer to "how much does the employer value your work". The answer is suboptimal in many ways (eg my guess is startups by default assign too much equity to the founders), but at least it provides a simple starting point; better to make up numbers and all that.

Rationally and ideally, you should just maximize the expected value of your actions, taking into account your potential influence on others and their costs, including opportunity costs. This just follows assuming expected utility theory axioms. It doesn’t matter that there are other agents; you can just capture them as part of your outcomes under consideration.
When you're assigning credit across other actors whose impacts aren't roughly independent, including for estimating their cost-effectiveness for funding, Shapley values (or something similar) can be useful. You want assigned credit to sum to 100% to avoid double counting or undercounting. (Credit for some actors can even be negative, though.)
But, if you were going to calculate Shapley values, which means estimating a bunch of subgroup counterfactuals that didn't or wouldn't happen, anyway, you may be able to just directly estimate how to best allocate resources instead. You could skip credit assignments (EDIT especially ex ante credit assignments, or when future work will be similar to past work in effects).

I think you can get closer to dissolving this problem by considering why you're assigning credit. Often, we're assigning some kind of finite financial rewards.
Imagine that a group of n people have all jointly created $1 of value in the world, and that if any one of them did not participate, there would only be $0 units of value. Clearly, we can't give $1 to all of them, because then we would be paying $n to reward an event that only created $0 of value, which is inefficient. If, however, only the first guy (i=1) is an "agent" that responds to incentives, while the others (1<=i<=n) are "environment" whose behaviour is unresponsive to incentives, then it is fine to give the first guy a reward of $1.
This is how you can ground the idea that agents who cooperate should share their praise (something like a Shapley Value approach), whereas rival agents who don't buy into your reward scheme should be left out of the shapley calculation.

I'll give general takes in another comment, but I just wanted to call out how I think that at least for some of your examples the assumptions are unrealistic (and this can make the puzzle sound worse than it is).
Take the case of "The funding of an organization and the people working at the org". In this case the must factors combine in a sub-multiplicative way rather than a multiplicative way. For it's clear that if you double the funding and double the people working at the org you should approximately double the output (rather than quadruple it). I think that Cobb-Douglas production functions are often a useful modelling tool here.
In the case of managers or the Forum I suspect that it's also not quite multiplicative -- but a bit closer to it. In any case I do think that after accounting for this there's still a puzzle about how to evaluate it.
The Forum went down this morning, for what is I believe the longest outage we've ever had. A bot was breaking our robots.txt and performing a miniature (unintentional) DOS attack on us. This was perfectly timed with an upgrade to our infrastructure that made it hard to diagnose what was going on. We eventually figured out what was going on and blocked the bot, and learned some lessons along the way. My apologies on behalf of the Forum team :(
The tl;dr is that trying to ban AI progress will increase the hardware overhang, and risk the ban getting lifted all of a sudden in a way that causes a dangerous jump in capabilities.
Background reading: this summary will rely on an understanding of hardware overhangs (second link), which is a somewhat slippery concept, and I myself wish I understood at a deeper level.

Effectiveness of regulation and the counterfactual

Your only other option is draconian regulation, which will be hard to do well and will unpredictable and bad effects.

Thanks. I think that your summary is great and touched on basically all the major points that I meant to address in my original Twitter thread. I just have one clarification.
I want to note that this argument was not spelled out very well, so I can understand why it might be confusing. I didn't mean to make a strong claim about whether we have a fixed budget of delays; only that it's possible. In fact, there seems to be a reason why we wouldn't have a fixed budget, since delaying now might help us delay later.
Nonetheless, delaying now means that we get more overhang, which means that we might not be able to "stop" and move through later stages as slowly as we're moving through our current stage of AI development. Even if the moratorium is lifted slowly, I think we'd still get less incremental progress later than if we had never had the moratorium to begin with, although justifying this claim would take a while, and likely requires a mathematical model of the situation. But this is essentially just a repetition of the point about overhangs stated in a different way, rather than a separate strong claim that we only get a fixed budget of delays.
For the first he got this notable comment from OpenPhil's Lewis Bollard. Honorable mention includes this post which I also remembered, doing good epistemic work fact-checking a commonly cited comparison.
Also, I feel that as the author, I get more credit than is due, it’s more of a team effort. Other staff members of Rethink Charity review my posts, help me to select topics, and make sure that I have to worry about nothing else but writing. And in some cases posts get a lot of input from other people. E.g., Kieran Greig was the one who pointed out the problem of fish stocking to me and then he gave extensive feedback on the post. My CEE of corporate campaigns benefited tremendously from talking with many experts on the subject who generously shared their knowledge and ideas.
Thanks JP! I feel I should point out that it's now basically my full time job to write for the EA forum, which is why there are quite many posts by me :)
If you're copy-pasting from a Google Doc, you can now copy-paste footnotes into the WYSIWYG editor in the following way (which allowed us to get around the impossibility of selecting text + footnotes in a Google Doc):
Publish your Google Doc to web
You can do this by clicking on File > Share > Publish to web
Then approve the pop-up asking you to confirm (hit "Publish")
Then open the link that you'll be given; this is now the published-to-web version of your document.
Select the whole text, including footnotes, and copy that. (If you'd like, you can now unpublish the document.)
Open the Forum text editor (WYSIWYG), and paste the selection.
We'll announce this in a top level post as part of a broader feature announcement soon, but I wanted to post this on my shortform to get this in to the minds of some of the authors of the Forum.
Thanks to Jonathan Mustin for writing the code that made this work.
If you're experiencing wrist pain, you might want to take a break from typing. But the prospect of not been able to interact with the world might be holding you back. I want to help you try voice input. It's been helpful for me to go from being scared about my career and impact to being confident that I can still be productive without my hands. (In fact this post is brought to you by nothing but my voice.) Right now I think you're the best fit if you:
Have ever written code, even a small amount, or otherwise feel comfortable editing a config file

Have a quiet room where you can talk to your computer
Make sure you have a professional microphone — order this mic if not, which should arrive the next day.
Then you can book a call with me. Make sure your mic will arrive by the time the call is scheduled.
woah! I haven't tried it yet but this is really exciting! the technical changes to the Forum have seemed impressive to me so far. I also just noticed that the hover drop-down on the username is more expanded, which is visually unappealing but probably more useful.
Here's a thought you might have: "AI timelines are so short, it's significantly reducing the net present value[1] of {high school, college} students." I think that view is tempting based on eg (1,2). However, I claim that there's a "play to your outs" effect here. Not in a "AGI is hard" way, but "we slow down the progress of AI capability development".

Some thoughts on optimal allocation for people who are selfless but nevertheless human.
Baseline: 40 hours a week.
Tiny brain: Work more get more done.
Normal brain: Working more doesn’t really make you more productive, focus on working less to avoid burnout.
Bigger brain: Burnout’s not really caused by overwork, furthermore when you work more you spend more time thinking about your work. You crowd out other distractions that take away your limited attention.
Galaxy brain: Most EA work is creative work that benefits from:
Real obsession, which means you can’t force yourself to do it.
Fresh perspective, which can turn thinking about something all the time into a liability.
Excellent prioritization and execution on the most important parts. If you try to do either of those while tired, you can really fuck it up and lose most of the value.
Here are some other considerations that I think are important:
If you work hard you contribute to a culture of working hard, which could be helpful for attracting the most impactful people, who are more likely than average in my experience to be hardworking.
Many people will have individual-specific reasons not to work hard. Some peopl
Thanks for writing this up – I'm really interested in answers to this and have signed up for notifications to comments on this post because I want to see what others say.
I find it hard to talk about "working harder" in the abstract, but if I think of interventions that would make the average EA work more hours I think of things like: surrounding themselves by people who work hard, customizing light sources to keep their energy going throughout the day, removing distractions from their environment, exercising and regulating sleep well, etc. I would guess that these interventions would make the average EA more productive, not less.
(nb: there are also "hard work" interventions that seem more dubious to me, e.g. "feel bad about yourself for not having worked enough" or "abuse stimulants".)
One specific point: I'm not sure I agree regarding the benefits of "fresh perspective". It can sometimes happen that I come back from vacation and realize a clever solution that I missed, but usually me having lost context on a project makes my performance worse, not better.

Maybe you’re suspicious of this claim, but if I think if you convinced me that JP working more hours was good on the margin, I could do some things to make it happen. Like have one saturday a month be a workday, say. That wouldn’t involve doing broadly useful life-improvements.
On “fresh perspective”, I‘m not actually that confident in the claim and don’t really want to defend it. I agree I usually take a while after a long vacation to get context back, which especially matters in programming. But I think (?) some of my best product ideas come after being away for a while.
Also you could imagine that the real benefit of being away for a while is not that you’re not thinking about work, but rather that you might’ve met different people and had different experiences, which might give you a different perspective.

I see. My model is something like: working uses up some mental resource, and that resource being diminished presents as "it's hard for you to work more hours without some sort of lifestyle change." If you can work more hours without a lifestyle change, that seems to me like evidence your mental resources aren't diminished, and therefore I would predict you to be more productive if you worked more hours.
As you say, the most productive form of work might not be programming, but instead talking to random users etc.

For the sake of argument, I'm suspicious of some of the galaxy takes.
I think relatively few people advocate working to the point of sacrificing sleep, prominent hard-work-advocate (& kinda jerk) rabois strongly pushes for sleeping enough & getting enough exercise.
Beyond that, it's not obvious working less hard results in better prioritization or execution. A naive look at the intellectual world might suggest the opposite afaict, but selection effects make this hard. I think having spent more time trying hard to prioritize, or trying to learn about how to do prioritization/execution well is more likely to work. I'd count "reading/training up on how to do good prioritization" as work
Agree re: the value of fresh perspective, but idk if the evidence actually supports that working less hard results in fresh perspective. It's entirely plausibly to me that what is actually needed is explicit time to take a step back - e.g. Richard Hamming Fridays - to reorient your perspective. (Also, imo good sleep + exercise functions as a better "fresh perspective" that most daily versions of "working less hard", like chilling at home)
TBH, I wonder if working on very different projects to reset your assumptions about the previous one or reading books/histories of other important project/etc works better is a better way of gaining fresh perspective, because it's actually forcing you into a different frame of mind. I'd also distinguish vacations from "only working 9-5", which is routine enough that idk if it'd produce particularly fresh perspective.
Real obsession definitely seems great, but absent that I still think the above points apply. For most prominent people, I think they aren't obsessed with ~most of the work their doing (it's too widely varied), but they are obsessed with making the project happen. E.g. Elon says he'd prefer to be an engineer, but has to do all this business stuff to make the project happen.
Also idk how real obsession develops, but it seems more

A few notes on organizational culture — My feeling is some organizations should work really hard, and have an all-consuming, startup-y culture. Other organizations should try a more relaxed approach, where high quality work is definitely valued, but the workspace is more like Google’s, and more tolerant of 35 hour weeks. That doesn’t mean that these other organizations aren’t going to have people working hard, just that the atmosphere doesn’t demand it, in the way the startup-y org would. The culture of these organizations can be gentler, and be a place where people can show off hobbies they’d be embarrassed about in other organizations.
These organizations (call them Type B) can attract and retain staff who for whatever reason would be worse fits at the startup-y orgs. Perhaps they’re the primary caregiver to their child or have physical or mental health issues. I know many incredibly talented people like that and I’m glad there are some organizations for them.
Here's an interesting tweet from a thread by Ajeya Cotra:
But I'm not aware of anyone who successfully took complex deliberate *non-obvious* action many years or decades ahead of time on the basis of speculation about how some technology would change the future.
I'm curious for this particular line to get more discussion, and would be interested in takes here.
Seems wrong to me. For example, Hamilton and Jefferson on the U.S. patent system. Also debates between Tesla and Edison on DC vs. AC and various policies associated with electricity. Also people working on nuclear regulation. Also people working on the early internet. Also lots of stuff around genetic engineering, the trajectory of which seems to have been shaped by many people taking deliberate action. Also, climate change, where a bunch of people did successfully invest in solar stuff which seems like it's now paying off quite well, and certainly didn't seem that obvious.
I don't know whether any of these count as "non-obvious". I feel like the "obvious" is doing all the work here, or something.

I feel like non-obvious is very load bearing here because my first thought is Joseph Bazalgette and the London Sewer system.
Note from the Forum team: The Forum was intermittently down for roughly an hour and change last night/this morning, due to an issue with our domain provider.
I've just released the first step towards having EA Forum tags become places where you can learn more about a topic after read a post. Posting about it because it's a pretty noticeable change:
The tag at the top of the post makes it easier to notice that there's a category to this post. (It's the most relevant core tag to the post.) We had heard feedback from new users that they didn't know tags were a thing.
Once you get to the tag page, there's now a header image. More changes to the tag pages to give it more structure are coming.
Maybe worth trying adding a (tiny) title over the tags, such as "see more posts about:"
Or adding the tags again at the bottom of the post with a similar title.
Anyway +1 to this, and I'm a big fan of the "tags" feature!
Consider time discounting in your cost-benefit calculations of avoiding tail risks
[Epistemic status: bit unendorsed, written quickly]
For many questions of tail risks (covid, nuclear war risk) I've seen EAs[1] doing a bunch of modeling of how likely the tail risk is, and what the impact will be, maybe spending 10s of hours on it. And then when it comes time to compare that tail risk vs short term tradeoffs, they do some incredibly naive multiplication, like life expectancy * risk of death.
Maybe if you view yourself as a pure hedonist with zero discounting, but that's a hell of a mix. I at least care significantly about impact in my life, and the impact part of my life has heavy instrumental discounting. If I'm working on growing the EA community, which is exponentially growing at ~20% per year, then I should discount my future productivity at 20% per year.
[This section especially might be wrong] So altruistically, I should be weighing the future at a factor of about (not gonna show my work) ∫400e−.2tdt times my productivity for a year, which turns out to be a factor of about 5.
Maybe you disagree with this! Good! But now this important part of the cost-benefit calcula... (read more)
Another interesting way this could diverge from the naive case is not by including discounting, but by considering how much more / less impactful you would be if you were one of the survivors of a nuclear war. I lean in the direction of thinking I would be less impactful, but maybe one would be more. This consideration doesn't apply to long covid, but seems to dominate the nuclear war considerations in my view.
In which JP tries to learn about AI governance by writing up a take. Take tl;dr: Overhang concerns and desire to avoid catchup effects seem super real. But that need not imply speeding ahead towards our doom. Why not try to slow everything down uniformly? — Please tell me why I’m wrong.
After the FLI letter, the debate in EA has coalesced into “6 month pause” vs “shut it all down” vs some complicated shrug. I’m broadly sympathetic to concerns (1, 2) that a moratorium might make the hardware overhang worse, or make competi... (read more)
1. I agree increasing the cost of compute or decreasing the benefits of compute would slow dangerous AI.
2. I claim taxing AI products isn't great because I think the labs that might make world-ending models aren't super sensitive to revenue-- I wouldn't expect a tax to change their behavior much. (Epistemic status: weak sense; stating an empirical crux.)
1. Relatedly, taxing AI products might differentially slow safe cool stuff like robots and autonomous vehicles and image generation. Ideally we'd only target LLMs or something.
3. Clarification: I think "hardware overhang" in this context means "amount labs could quickly increase training compute (because they were artificially restrained for a while by regulation but can quickly catch up to where they would have been)"? There is no standard definition, and the AI Impacts definition you linked to seems inappropriate here (and almost always useless-- it was a useful concept before the training is expensive; running is cheap era).
When American sports players try to trash talk their opponents, the opponents will sometimes retort with the word "scoreboard" along with pointing at the screen showing that they plainly have more points.

What should my prior be about the likelihood of being at the hinge of history? I feel really interested in this question, but haven't even fully read the comments on the subject. TODO.
How much evidence do I have for the Yudkowsky-Bostrom framework? I'd like to get better at comparing the strength of an argument to the power of a study.
Suppose I think that this argument holds. Then it seems like I can make claims about AI occurring because I've thought about the prior that I have a lot of influence. I keep going back and forth about whether this is a valid move. I think it just is, but I assign some credence that I'd reject it if I thought more about it.
What should my estimate of the likelihood we're at the HoH if I'm 90% confident in the arguments presented in the post?
This first shortform comment on the EA Forum will be both a seed for the page and a description.
Shortform is an experimental feature brought in from LessWrong to allow posters a place to put quickly written thoughts down, with less pressure to make it to the length / quality of a full post.
Thus starts the most embarrassing post-mortem I've ever written. The EA Forum went down for 5 minutes today. My sincere apologies to anyone who's Forum activity was interrupted. I was first alerted by Pingdom, which I am very glad we set up. I immediately knew what was wrong. I had just hit "Stop" on the (long unused and just archived) CEA Staff Forum, which we built as a test of the technology. Except I actually hit stop on the EA Forum itself. I turned it back on and it took a long minute or two, but was soon back up. ... Lessons learned: * I've seen sites that, after pressing the big red button that says "Delete", makes you enter the name of the service / repository / etc. you want to delete. I like those, but did not think of porting it to sites without that feature. I think I should install a TAP that whenever I hit a big red button, I confirm the name of the service I am stopping. * The speed of the fix leaned heavily on the fact that Pingdom was set up. But it doesn't catch everything. In case it doesn't catch something, I just changed it so that anyone can email me with "urgent" in the subject line and I will get notified on my phone, even if it is on silent. My email is jp at organizationwebsite.
Alright, the title sounds super conspiratorial, but I hope the content is just boring. Epistemic status: speculating, somewhat confident in the dynamic existing.
Climate science as published by the IPCC tends to
1) Be pretty rigorous
2) Not spend much effort on the tail risks
I have a model that they do this because of their incentives for what they're trying to accomplish.
They're in a politicized field, where the methodology is combed over and mistakes are harshly criticized. Also, they want to show enough damage from climate change to make it clear that it's a good idea to institute policies reducing greenhouse gas emissions.
Thus they only need to show some significant damage, not a global catastrophic one. And they want to maintain as much rigor as possible to prevent the discovery of mistakes, and it's easier to be rigorous about things that are likely than about tail risks.
Yet I think longtermist EAs should be more interested in the tail risks. If I'm right, then the questions we're most interested in are underrepresented in the literature.
For a long time the EA Forum has struggled with what to call its tag / wiki thing. Our interface had several references to "this wiki-tag". As part of our work to improve the tagging feature, we've now renamed it to Topics.
I should write up an update about the Decade Review. Do you have questions about it? I can answer them here, but it will also help me inform the update.
Do you use the Forum? (Probably, considering.) Do you have feelings about the Forum?
If you send me a PM, one of the CEA staffers running the Forum (myself or Aaron) will set up a call call where you can tell me all the things you think we should do.
I'm wondering about the possibility to up-vote one's own posts and comments. I find that a bit of an odd system. My guess would be that someone up-voting their own post is a much weaker signal of quality than someone up-voting someone else's post.
Also, it feels a bit entitled/boastful to give a strong up-vote to one's own posts and comments. I'm therefore reluctant to vote on my own work.
Hence, I'd suggest that one shouldn't be able to vote on one's own posts and comments.
By default your comments are posted with a regular upvote on them posts with a strong upvote on them. The fact that it's default seems to me to lower my concern about boastfulness. Although I do think it's possible the Forum shouldn't let you change away from those defaults. When I observed someone strong-upvoting their comments on LW, I found it really crass.
As to why not change the default, I do think that you by default endorse your comments and posts. This provides useful info to people, because if you're a user with strong upvote power, your posts and comments enter more highly rated. This provides a small signal to new users about who the Forum has decided to trust. And it makes it less likely that you'll see a dispiriting "0" next to your comment. OTOH, we don't count self-votes for the purposes of calculating user karma, so maybe by consistency we shouldn't show it.

I am in favor of these defaults and also in favor of disallowing people to change them. I know of two people on LW who have admitted to strong-upvoting their comments, and my sense is that this behavior isn't that uncommon (to give a concrete estimate: I'd guess about 10% of active users do this on a regular basis). Moreover, some of the people who may be initially disinclined to upvote themselves might start to do so if they suspect others are, both because the perception that a type of behavior is normal makes people more willing to engage in it, and because the norm to exercise restrain in using the upvote option may seem unfair when others are believed to not be abiding by it. This dynamic may eventually cause a much larger fraction of users to regularly self-upvote.
So I think these are pretty strong reasons for disallowing that option. And I don't see any strong reasons for the opposite view.

I guess there are two different issues:
1) Should comments and posts by default start out with positive karma, or should it be 0?
2) Should it be possible for the author to change the default level of karma their post/comment starts out with?
This yields at least four combinations:
a) Zero initial karma, and that's unchangeable.
b) Zero initial karma by default, but you could give up-votes (including strong up-votes) to your own posts, if you wanted to.
c) A default positive karma (which is a function of your total level of karma), which can't be changed.
d) A default positive karma, which can be increased (strong up-vote) or decreased (remove the default up-vote). (This is the system we have now.)
My comments only pertained to 2), whether you should be able to change the default level of karma - e.g. to give strong up-votes to your own own posts and comments. On that, you found it "crass" when someone did that. You also made this comment:
This rather seems to relate to 1).
As stated, I don't think one should be able to change the default level of karma. This would rule out b) and d), and leave a) and c). I have a less strong view on how to decide between those two systems, but probably support a).

I agree with you and Pablo that I'd rather see it unchangeable. My prioritization basically hinges on how common it is. If Pablo's right and it's 10%, that seems concerning. I've asked the LW team.

Making it unchangeable also seems reasonable to me, or at least making it so that you can no longer strong-upvote your own comments.
Strong-upvoting your own posts seems reasonable to me (and is also the current default behavior)
Did you know you can see strong self upvotes for all users?
You can see the this at the user level (how much they do this in total) and I’m 80% sure you can see this at the comment/post level for each user.
This might mitigate your concerns and the related activity might finally produce a report where I am ranked #1.

Please fix the EA forum search engine and/or make it easier to find forum posts through Google.

Pablo

On the whole, I really like the search engine. But one small bug you may want to fix is that occasionally the wrong results appear under 'Users'. For example, if you type 'Will MacAskill', the three results that show up are posts where the name 'Will MacAskill' appears in the title, rather than the user Will MacAskill.
EDIT: Mmh, this appears to happen because a trackback to Luke Muehlhauser's post, 'Will MacAskill on Normative Uncertainty', is being categorized as the name of a user. So, not a bug with the search engine as such, but still something that the EA Forum tech team may want to fix.

Oh the joys of a long legacy of weird code. I've deleted those accounts, although I'm sad to report that our search engine is not smart enough to figure out that "Will MacAskill" should return "William_MacAskill"

Yeah, you can add lots of additional fields. It also has like 100 options for changing the algorithm (including things like changing the importance of spelling errors in search, and its eagerness to correct them), so playing around with that might make sense.

Curious what the problem with the current search engine is? Agree that it's important to be able to find forum posts via Google, which is currently an EA Forum specific issue, but improvements to the search likely also affect LessWrong, so I am curious in getting more detail on that.

Kirsten

Posts are not listed in order of relevance. You need to know exact words from the post you're searching for in order to find it - preferably exact words from the title.
For example, if I wanted to find your post from four days ago on long term future grants and typed in "grants", your post wouldn't appear, because your post uses the word "grant" in the title instead.
2
Ben Pace
5y
FYI, this was a very helpful concrete example.
On reflection your reasoning is false though - it's not because the post uses the word 'grant'. If I search 'grant' I get almost identical results, certainly the first 6 are the same. If I search 'ltf grants' I get the right thing even though neither 'ltf' or 'grants' is in the title. I also think that it's not like there aren't a lot of other posts you could be searching for with the word 'grant' - it isn't just random other posts, there are *many* posts withing ~2x karma that have that word in the title.
Still, I share a vague sense that something about search is not quite right, though I can't put my finger on it.

(Edit: This was written before Khorton edited a concrete example into their comment)
Interesting. I haven't had many issues with the search. I mostly just wanted it to have more options that I can tweak (like restricting it to a specific time period and author). If you know of any site (that isn't a major search engine provider) that has search that does better here, I would be curious to look into what technology they use (we use Algolia, which seems to be one of the most popular search providers out there, and people seem to generally be happy with it). It might also be an issue of configuration.

Speaking to the google search results – It's pretty hard to just rise up the google rankings. We've done the basic advice: the crawled page contains the post titles and keywords, made sure google finds the mobile view is satisfactory. It's likely there more we can do but it's not straightforward. Complicating matters is that during the great spampocalypse in May, we were hit with a punitive action from google, because we were polluting their ranking algorithm with spam links. You may remember a time when there were no results linking to posts at all. We fixed it, but it's possible (and I'd guess likely) that we're still getting dinged for that. Unfortunately, google gives us no way of knowing.

NB: We're now done planning Q4. Suggestions are still valuable, but consider holding off on further comments for a bit, we have a final draft of a post that's about to give a lot more context. Of course, if you've got a useful comment you'd otherwise forget about, I don't mind continuing to answer.

I clicked on 'go to Permalink' for this post, because I was going to send it to a friend, but I don't think it did anything.

What happens when you do that is that now your url bar in your browser points to this post, with a fancy standalone version of the comment above the post. Unfortunately, because the post doesn't actually change, you aren't navigating to a new page and your scroll stays where it is. It's a new feature from LessWrong, I've filed a bug report with them.

This is an interesting question. It would certainly prevent a bunch of bad behavior and force people to be more intentional in their voting. Here are I think the main reasons we / LW have talked about it but not implemented it:
a) Some people just read way more of the Forum than others. Should their votes have less weight because they must be spread over many comments?
b) I don't want users to have to think about conserving their voting resources. If they like something, I want them to vote something and move on. Karma is fun, but the purpose of the site is the content.

We could a) put that data on the start of every post or b) put it under a menu option under the ... menu. I think (a) wouldn't provide enough value to balance the cost of busying the UI, which is currently very sparse and the more valuable for it. I don't expect (b) would be used much. I don't have the data to back this up (yet! I really want to be able to easily check all of these) but I guess most people don't click on those menu buttons very often.

My guess is that it'll be hard to beat copy and pasting. Copy and pasting of styling works fairly well and is a pretty simple C-c,C-v.

This one's been requested a few times. My thought is that a well written post has a summary or hook in the first paragraph. Aaron is more optimistic though.
With this one and the keywords box, I'd tend heavily towards leaving it optional but encouraged. I want to keep posting easy, and lean towards trusting the authors to know what will work with their post.
I want to write a post saying why Aaron and I* think the Forum is valuable, which technical features currently enable it to produce that value, and what other features I’m planning on building to achieve that value. However, I've wanted to write that post for a long time and the muse of public transparency and openness (you remember that one, right?) hasn't visited.

We've been experiencing intermittent outages recently. Multiple possible causes and fixes have not turned out to fix it, so we're still working on it. If you see an error saying: "503 Service Unavailable: No healthy endpoints to handle the request. [...]" Try refreshing, or waiting 30 seconds and then refreshing; they're very transient errors. Our apologies for the disruption.
Here’s a puzzle I’ve thought about a few times recently:
The impact of an activity (I) is due to two factors, X and Y. Those factors combine multiplicatively to produce impact. Examples include:
Let’s assume in all of these scenarios that you are only one of the players in the situation, and you can only control your own actions.
From a counterfactual analysis, if you can increase your contribution by 10%, then you increase the impact by 10%, end of story.
From a Shapley Value perspective, it’s a bit more complicated, but we can start with a prior that you split your impact evenly with the other players.
Both these perspectives have a lot going for them! The counterfactual analysis has important correspondences to reality. If you do 10% better at your job the world gets 0.1I better. Shapley Values prevent the scenario where the multiplicative impact causes the involved agents to collectively contribute too much.
I notice myself... (read more)
I'm annoyed at vague "value" questions. If you ask a specific question the puzzle dissolves. What should you do to make the world go better? Maximize world-EV, or equivalently maximize your counterfactual value (not in the maximally-naive way — take into account how "your actions" affect "others' actions"). How should we distribute a fixed amount of credit or a prize between contributors? Something more Shapley-flavored, although this isn't really the question that Shapley answers (and that question is almost never relevant, in my possibly controversial opinion).
Happy to talk about well-specified questions. Annoyed at questions like "should I use counterfactuals here" that don't answer the obvious reply, "use them FOR WHAT?"
FOR WHAT?

The Forum went down this morning, for what is I believe the longest outage we've ever had. A bot was breaking our robots.txt and performing a miniature (unintentional) DOS attack on us. This was perfectly timed with an upgrade to our infrastructure that made it hard to diagnose what was going on. We eventually figured out what was going on and blocked the bot, and learned some lessons along the way. My apologies on behalf of the Forum team :(
I'd like to try my hand at summarizing / paraphrasing Matthew Barnett's interesting twitter thread on the FLI letter.[1]
The tl;dr is that trying to ban AI progress will increase the hardware overhang, and risk the ban getting lifted all of a sudden in a way that causes a dangerous jump in capabilities.
Background reading: this summary will rely on an understanding of hardware overhangs (second link), which is a somewhat slippery concept, and I myself wish I understood at a deeper level.

Effectiveness of regulation and the counterfactual
It is hard to prevent AI progress. There's a large monetary incentive to make progress in AI, and companies can make algorithmic progress on smaller models. "Larger experiments don't appear vastly more informative than medium sized experiments."[2] The current proposals on the table on ban the largest runs.
Your only other option is draconian regulation, which will be hard to do well and will unpredictable and bad effects.
Conversely, by default, Matthew is optimistic about companies putting lots of effort into alignment. It's economically incentivized. And we can see this happening: OpenAI has put more effort in... (read more)
Appreciation post for Saulius
I realized recently that the same author that made the corporate commitments post and the misleading cost effectiveness post also made all three of these excellent posts on neglected animal welfare concerns that I remembered reading.
Fish used as live bait by recreational fishermen
Rodents farmed for pet snake food
35-150 billion fish are raised in captivity to be released into the wild every year
For the first he got this notable comment from OpenPhil's Lewis Bollard. Honorable mention includes this post which I also remembered, doing good epistemic work fact-checking a commonly cited comparison.
Also, I feel that as the author, I get more credit than is due, it’s more of a team effort. Other staff members of Rethink Charity review my posts, help me to select topics, and make sure that I have to worry about nothing else but writing. And in some cases posts get a lot of input from other people. E.g., Kieran Greig was the one who pointed out the problem of fish stocking to me and then he gave extensive feedback on the post. My CEE of corporate campaigns benefited tremendously from talking with many experts on the subject who generously shared their knowledge and ideas.
Thanks JP! I feel I should point out that it's now basically my full time job to write for the EA forum, which is why there are quite many posts by me :)

How hard should one work?
Some thoughts on optimal allocation for people who are selfless but nevertheless human.
Baseline: 40 hours a week.
Tiny brain: Work more get more done.
Normal brain: Working more doesn’t really make you more productive, focus on working less to avoid burnout.
Bigger brain: Burnout’s not really caused by overwork, furthermore when you work more you spend more time thinking about your work. You crowd out other distractions that take away your limited attention.
Galaxy brain: Most EA work is creative work that benefits from:
Here are some other considerations that I think are important:

I've just released the first step towards having EA Forum tags become places where you can learn more about a topic after read a post. Posting about it because it's a pretty noticeable change:
The tag at the top of the post makes it easier to notice that there's a category to this post. (It's the most relevant core tag to the post.) We had heard feedback from new users that they didn't know tags were a thing.

Consider time discounting in your cost-benefit calculations of avoiding tail risks
[Epistemic status: bit unendorsed, written quickly]
For many questions of tail risks (covid, nuclear war risk) I've seen EAs[1] doing a bunch of modeling of how likely the tail risk is, and what the impact will be, maybe spending 10s of hours on it. And then when it comes time to compare that tail risk vs short term tradeoffs, they do some incredibly naive multiplication, like life expectancy * risk of death.
Maybe if you view yourself as a pure hedonist with zero discounting, but that's a hell of a mix. I at least care significantly about impact in my life, and the impact part of my life has heavy instrumental discounting. If I'm working on growing the EA community, which is exponentially growing at ~20% per year, then I should discount my future productivity at 20% per year.
[This section especially might be wrong] So altruistically, I should be weighing the future at a factor of about (not gonna show my work) ∫400e−.2tdt times my productivity for a year, which turns out to be a factor of about 5.

Things I'm confused about after reading Will's post, Are we living at the most influential time in history?:
What should my prior be about the likelihood of being at the hinge of history? I feel really interested in this question, but haven't even fully read the comments on the subject. TODO.
How much evidence do I have for the Yudkowsky-Bostrom framework? I'd like to get better at comparing the strength of an argument to the power of a study.
Suppose I think that this argument holds. Then it seems like I can make claims about AI occurring because I've thought about the prior that I have a lot of influence. I keep going back and forth about whether this is a valid move. I think it just is, but I assign some credence that I'd reject it if I thought more about it.

Shortform is an experimental feature brought in from LessWrong to allow posters a place to put quickly written thoughts down, with less pressure to make it to the length / quality of a full post.
Thus starts the most embarrassing post-mortem I've ever written.
The EA Forum went down for 5 minutes today. My sincere apologies to anyone who's Forum activity was interrupted.
I was first alerted by Pingdom, which I am very glad we set up. I immediately knew what was wrong. I had just hit "Stop" on the (long unused and just archived) CEA Staff Forum, which we built as a test of the technology. Except I actually hit stop on the EA Forum itself. I turned it back on and it took a long minute or two, but was soon back up.
...
Lessons learned:
* I've seen sites that, after pressing the big red button that says "Delete", makes you enter the name of the service / repository / etc. you want to delete. I like those, but did not think of porting it to sites without that feature. I think I should install a TAP that whenever I hit a big red button, I confirm the name of the service I am stopping.
* The speed of the fix leaned heavily on the fact that Pingdom was set up. But it doesn't catch everything. In case it doesn't catch something, I just changed it so that anyone can email me with "urgent" in the subject line and I will get notified on my phone, even if it is on silent.

On the incentives of climate science
Alright, the title sounds super conspiratorial, but I hope the content is just boring. Epistemic status: speculating, somewhat confident in the dynamic existing.
Climate science as published by the IPCC tends to
1) Be pretty rigorous
2) Not spend much effort on the tail risks
I have a model that they do this because of their incentives for what they're trying to accomplish.
They're in a politicized field, where the methodology is combed over and mistakes are harshly criticized. Also, they want to show enough damage from climate change to make it clear that it's a good idea to institute policies reducing greenhouse gas emissions.
Thus they only need to show some significant damage, not a global catastrophic one. And they want to maintain as much rigor as possible to prevent the discovery of mistakes, and it's easier to be rigorous about things that are likely than about tail risks.
Yet I think longtermist EAs should be more interested in the tail risks. If I'm right, then the questions we're most interested in are underrepresented in the literature.
For a long time the EA Forum has struggled with what to call its tag / wiki thing. Our interface had several references to "this wiki-tag". As part of our work to improve the tagging feature, we've now renamed it to Topics.
I should write up an update about the Decade Review. Do you have questions about it? I can answer them here, but it will also help me inform the update.
We're planning Q4 goals for the Forum.
Do you use the Forum? (Probably, considering.) Do you have feelings about the Forum?
If you send me a PM, one of the CEA staffers running the Forum (myself or Aaron) will set up a call call where you can tell me all the things you think we should do.
I'm wondering about the possibility to up-vote one's own posts and comments. I find that a bit of an odd system. My guess would be that someone up-voting their own post is a much weaker signal of quality than someone up-voting someone else's post.
Also, it feels a bit entitled/boastful to give a strong up-vote to one's own posts and comments. I'm therefore reluctant to vote on my own work.
Hence, I'd suggest that one shouldn't be able to vote on one's own posts and comments.
I think strong upvoting yourself should either be the default (opt-out), or impossible. It shouldn't be opt-in, because this rewards self-promotion.
